BURLONEY Ir. MARTIN, OF SAULSBU'RY, TENNESSEE.

SAFE.

To all whom it may concern.

Be it known that I, BURLONEY L. MaR'rIN, a citizen of the United States, residing at Saulsbury, in the county of Hardeman and State of Tennessee, have invented new and useful Improvements in Safes, of which the following is a specification.

This invention relates to improvements 1n safes and especially with reference to means for venting the force of an exploslon in the event that an attempt is made to open the safe by explosives and to prevent in ury to the safe from such cause, the invention consisting in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings :Figure 1 is a front elevation of a safe constructed in accordance with my invention, with the doors removed. Fig. 2 is a vertical transverse sectional view of the safe on a plane extending through the front and rear walls of the safe. Fig. 3 is a vertical sectional view on the plane indicated by the line aa of Fig. 2. Fig. 1 is a horizontal sectional view of thesame on the plane indicated by the line bb of Fig. 2. Fig. 5 is a detail elevation, showing the inner side of the outer door.

The outer walls of the safe are indicated at l and the inner walls at 2, spaced from the outer walls. The bottom of the safe is indicated at 3, the top at 4, the, inner bottom, of the inner safe structure is indicated 1 at 5, and the top of the inner safe structure is indicated at 6. The outer door 7 and inner door 8 and generally the entire structure of the safe may be as desired. The inner safe structure is here shown as com-' prising a compartment 9 and a smaller compartment 10.

In accordance with my invention I provide a venting duct 11 which extends through openings in the safe bottom 3 and the bottom 5 of the inner safe structure and con- Specification of Letters Patent.

portion of the compartment 9, and which while so strong as to hold the valve firmly in closed position are yet sufficiently yieldable to permit the valve to be opened by the force of an explosion in the safe so as to cause the valve to vent the explosive gases and thus protect the Walls or doors of the safe from injury by the explosion, the springs being weaker than the walls or the doors and hence the valve will open and vent the safe and prevent injury thereto.

The compartment 9 is connected to the compartment 10 by venting tubes 14 which are here shown as arranged in the spaces between the inner and outer walls of the safe. Hence if an explosion occurs in the compartment 10, from an explosive which has been inserted in said compartment by drilling the safe, the explosion and the gases will be vented from said compartment 10 to the compartment 9 through the tubes 1 1 and from the compartment 9 to the outer air past the valve 12 and through the venting duct 11.

The bottom of the safe is provided on its lower side with a depending flange 15 which terminates a slight distance above the floor of the vault or room in which the safe is used, thus affording an escape for the explosive gases from the lower end of the venting duct 11 and also preventing access to the valve so that the latter cannot become wedged by design and rendered inoperative.

I also provide vertically arranged venting pipes 16 near the lower corners of the safe and which extend through the bottom thereof and are open at their upper and lower ends. A gutter bar 17 connects the upper ends of these vent tubes 16 and is arranged at the bottom of the vertical space between the inner and outer doors. If nitroglycerin or other explosive is inserted between the doors it is caught in ing said inner and outer structures and open at its inner and outer ends a valve to close said duct, and a spring to normally hold said valve in closed position said inner structure having a plurality of compartments and a duct connecting said compartments and arranged in a space between the inner and outer structures.

.2,. A safe comprising an outer structure,

Copies of this patent may be obtained for an inner structure, a venting duct open at its inner and outer ends communicating with the inner structure andpasslng through the outer structure, a spring actuated valve for closing said duct and a flange formed on the outer structure and surrounding the end of the duct connected therewith, said flange being adapted to serve as a guard for sai valve.
